Letters Patent No. 61.843, dated February 5, 1867.

HAND-STAMP.

TO ALL WHOM IT MAY CONOERN:

Be it known that I, WILLIAM B. MASON, of Boston, Suffolk county, State of Massachusetts, have invented certain new and useful improvements in IIand-Stamps; and I ,do hereby declare the following descriptionl and accompanying drawings are sudicient to enable any person skilled in the art or science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment.

The nature of my invention and improvements consists in the combination and arrangement of devices described and claimed in the following specification, and which tend to make more perfect my improved hand-stamp. In the accompanying drawings- Figure 1 is a'front elevation of a handstamp, with my improvements.

Figure 2 is an elevation of the opposite side from that shown in tig. 1.

Figure -3 is an elevation of one edge.

In the above-mentioned drawings,A A are slotted stands,`supporting the b ar B, which stands and bar forni the frame of the machine, and they may be made in the form shown, or in such other form as will answer the purpose. The stands A may be fastened to the bar B with screws, as shown in the drawings, or the bar and stands may be made in one piece, as may be preferred. `I The stamping-plate or type C are fastened to the plate D, which is fitted to traverse between the stands A A, and is provid'edwith lugs E at the ends, which traverse in the slots F in the stands A. The transverse rody Gis fastened to the upper side of the plate D,`and works or traverses through a hole in the bar B, and is provided with a knob, H, at its upper end, which is struck with the hand to make anl impression with the stamp; and, after the impression is made, the spring I around the rod G between the bar B and knob 'H raises the rod, ,with the plate D and type, to the under side ofthe bar B, and holdsthem there until the knob is struck again to make another impression. I make some projections', J J, on the stand A, for the journals of the rook-shaft K of the inking-pad, which acts automatically",` and is thrown and pressed against the 'type or plate by a coiled spring arranged in the projection J, and shown by dotted lines in iig. 3, one end of the spring being fastened to the shaft and the otherto the inside of the projection J. The inking-pad consists of the plate Ivfastened to the' shaft K, with an inkingapron M around the plate and shaft K, which has the disk N fastened to it,'witl1'one notch in it, for the pawl P to catch into and hold the pad perpendicular out of the way of the plate and type in their ascent, after making an impression. The pawl P is pressed down by the spring Q fastened to the bar B. The pawl P is fastened to the bar B so as to vibrate, and when the plate D rises up to the bar B,`it lifts the pawl and releases the pad, and it swings in up against the type, and inks it ready for another impression. 4When the plate is pressed down to make an impression, a projection, S, at one corner strikes the rib R on the plate L, and swings the inking-pad down perpendicular out of the wayof the type andplate, and the pawl P catches in-the notch of the disk, and holds it until the plate D rises and releases it, as above mentioned.

Having described my improved hand-stamp, I will statemy claim as follows: i

1. I claim the disk N, with a notch, in combination with the pawl P, to hold the inking-pad clear of the type and plate when they are raised.

2. I claim so arranging and operating the plate D that it shall. release the pawl P and let the inking-pad swingagainst the typeplate, and ink it, substantially as described.

WILLIAM B. MASON.
